Photographer's Note

I took this photo in the Mangabeiras Park (a big green park in the highest part of my city). This bird was busy because it was trying to fish something in a small lake which didn't appear in the image. Then it didn't notice that I was so close.
I was using a domestic kodak camera.

Bienvenue, Welcome on TE.
I'm glad you found out the way to resize your photo.

On first sight I can say there are 3 little mistakes that easily can be avoided a next time. While shooting or after shot with a PP program like Photoshop Elements.
I loaded a WorkShop to let see you the mistakes:

Just a very quick PP (post-processing)
1/ Adjusted contrast - The image was not bright enough and the contrasts too soft.

2/ Adjusted level - (About the same as above)

3/ Cropped the image to get the bird a bit more out of center. It's "mostly" nicer to get your main object a little bit out of center. There is a rule which is called "Rule of third" like here and that could help you understand how to build a composition - * * * But, in my opinion, it's not always necessary to follow that rule, you can also follow your feeling about the place of the main object in your composition. Here the rule of third works best...

Also cropped the lower part of the picture and the green basket which was not a nice object and could be taken away as it is not a "nice" part of the composition.
